To all whom it may concem:

.Be it known that I, THOMAS D1; L.-:\1\L1RE, a citizen of the United States, residing at 'Tooele City, in the county ot'Tooele and State of Utah, have invented anew and use 7 ful Concrete-Culvert Mold, of which the following is a specification". This invention relates crete culverts. b b

,Theobject of the invention is to provide cheaply constru'ct-ed, easily set "up n and Another object is-to make a. mold of this proceeds, the invention resides in the combi nation. and arrangement of parts and. in the details of construction hereinafter described --and -clai1ned,; it being understoodfithat partingifrom the spirit of theinvention.

ber thereof. I I I I The top mold shown in Figs. 1 tot comprises an outer member land an inner member 10 shaped according-to the shape of theculvert to be molded, thefinner member Fig. 13 is-a similar view of another mem- 10 being smaller than the'puter member and spaced therefrom to form the concrete re- ,CGIVlHg chamber 20 between them.

' changes injthe precise embodiment of the invention herein disclosed may be madelwith inthe scope otwhat is claimed without de- Each sectionfis.cornposedof a plurality of separably connected. plates or. sections 9, 7 three .being here shown; These transverse I sections. 9 adapt ,theimold to be more easily Yassembled.5 ,The side members of thejouter mold sections are secured'together atftheirv lower ends by plates 23 and 2%! arranged one ion-"the inner and the other on the outer face:-

of'theisection and secured bybolts25.v Ea'ch of theseside section's' as'shown in Fig. 2 are provided with afpluralityfof series ot ape'n tunes 26 and 27and with" other apertures 28 whic'hilatterare transversely alined. These apertures are designed for the adiustment of the mold sections. f v 1' The innerstection 10 is composed of. a

plurality,ofsectionsill; 12, 13, 14 and 15 the meeting. edges of which ha've intu'rned longitudinally extending flanges 716,1 the flange of one section be ng equipped with headed studs .or bolts .17. and the adjacent flange with key hole slots. 18. to receive" said cross sect-ion and the 7 legs or side portions thereof are held spacedfby, spacers 2 1 which bolt heads and-thus detachably vconnect the sections oft-he innermoldmembervlO.

\Yhile the outsidemold member-1 is made in three transverse sections 9 the inside mold member 10 is made in "one sectionasdeep as the mold should be.

the head wall to designed torest on The advantage or reason for making the outside mold 1 in three sections is that in setting up the mold the inside member is first set up, then one-third of the outsidemeld is set up and one-third of the concrete is placed between the mold members. Then the second transverse section of the outer mold-member is set up and more concrete is placed between them and finally the third-section is set up and the space filled with concrete. By placing the concrete in this manner'it is much easierto handle than if it were placed inbne deep sestis V The head jwall mold is shown at and is connected with one end of the top mold section 7 as shown in Fi 11 and com. rises I D v a member 51 having its inner edgec'urved their ends as shownat= t6 so th'atwhenthe as shown at to fit the outer face of the n ldsec i 7 and i esuipp ed Wl ha nst dnsfials 5. o bo ted Q$9 tl0 7 with e bi s?

End plates-'43 are arranged at opposite ends of the bottom mold 10 and are secured by rods 44 extendinglongitudinally-of the molds under the sectionsfnl and as is shown clearly in Figs. 7 and 8. These plates d3 have rectilinear lower edges 45 while thjeir upper edges incline 'fronr th -eentertewa1-d the edges 4L6 of the end plates itw-ill be of u'n'it'orm thickness throughout except atthe sides which fill the troughs 35 to provide abuttingshoulders for cooperation with the top portion of the culvert which is-molded in the molds hereinbefore described and shown in; Figs. 1 to 6. 4 It is of course understood that the width of the mold 10 may be varied by removing or nserting one or more of the'lnteri'nediate sections 37.

In making a. full sized culvert there will .be three upright sections besides the main body of the inold'an dfthe 'outside ot" the the mold which i is made in three sections is wider than thei inside pa'rt lO .plings" which un iteflthe qseetrons differ there will be no chance of the "moldeninterchanging the couplings and so spoiling the culvert.

The height "of the toportion of the by having the three cow culvert maybe varied-bychanging-theiloca tion of the spacers-21 which is accomplished by adjusting the bolts 22 in the apertures26. In Fig.1 6 theintermediate sectionsjof both the top and the bottom are removed and the side sections connected to form' a i mold-z lion a small culvert. t t y In the use of the tep' mold the :head wall mold being attachedtoi one end thereof, said moldis set up in uprightp sition as gshown in Fig. 11 with thehead wall 1 v on the supporting platform55. lt isunderstood that the outside section l of-the top mold is formedinthree partsorsections for convenience and by placing thebottomzsection in position firs't renders: it easier in pouring and forming the; when and which will insure a smoothsurface to the culvert. When the space between the mold sections is filled, to the tOp-0f ;l l1e bottonr section then the second section isplaoed 'and-fcement iold resting attached it will form the top end of the culvert with this head wall made integral therewith. The respective sections are placed end on end as the pouring proceeds thus rendering the making easier to accomplish.

I claim: I

1. A top mold for a culvert comprising inner and outer spaced walls to form a concrete receiving space between them, said walls being formed of detachably connected sections, the inner wall including three ].ongitudinally extending inserts with uprights connected with the side edges thereof, the outer wall including transversely arranged sections connected at their lower ends by plates positioned on opposite faces thereof and bolted thereto.

2. A top mold of the class described c0111- prising inner and outer spaced walls, the

outer wall being formed in transversely arranged sections detachably connected and adapted to be secured to the inner wall successively so that the mold may be filled and handled with a. minimum amount of labor.

3. A top mold for culverts comprising inner and outer spaced walls connected together, the outer wall being formed of a plurality of longitudinally extending sections having outturned abutting flanges, and a longitudinally split tube engaging said flanges to hold said sections assembled.

4;. A top mold for culverts comprising inner and outer spaced walls connected together. the outer wall being formed of a a plurality of longitudinally extending sections having outturned abutting. flanges,

said flanges being folded to form beads,

longitudinally split tubes slidably mounted on and encompassing said flanges to hold the sections assembled.

5. A culvert mold including a b0ttom member composed of aplurality of detachably connected sections, the side sections inelining from the inner toward the outer sides thereof and having upstanding flanges along with their outer edges with troughs at the bases thereof. I

7. A culvert mold including a bottom member composed of a plurality of sections having outturned abutting flanges, U-shaped connectors straddling said flanges and secured to one of them andloosely receiving the other. i

8. A top mold for culverts comprising inner and outer spaced walls connected together, the inner wall extending beyond the outer wall at one end thereof" and a head as my own, I have hereto aflixed my'sig-' nature.
